(01.237-79) This invention is directed to new and useful improvements in wall radiator enclosure of the type that is usually installed in a building during its construction. This type of enclosure comprises generally a casing surrounding the radiating means open at its bottom and top to permit circulation of air therethrough by convection and a damper means Fig. 2 is a vertical cross sectional view taken along line 2-2 of Fig. 1. ' ' Y Fig. 3 is a sectional view taken along line 3-3 of Fig. 2. ' Fig. 4 is an enlarged detail view of the securing meansshown in the uppermost part of Fig. 2. Fig. 5 is a sectional view similar to that of Fig. 2 of a slightly dilîerent form of enclosure positioned above the radiating means to control embodying this invention. the volume of heated air passing through the 10 casing. Fig. 6 is a cross-sectional view taken on line E-Sof Fig. 5. In modern `building construction steel window ' In detail the enclosure comprises a. back plate I, a front assembly 2 and a damper assembly 3. The upper edge of back plate I is bent to hori ‘zontal position to form a flange 6 extending from the plate I in a direction away from the wall 5 frame and sash is commonly used to increase the ñreprooñng of the building and inasmuch as the radiating means is generally positioned adjacent a window the enclosure must be constructed to lit and be secured to such steel construction. adjacent which the enclosure is to be positioned.

In the'drawings: 20 are outwardly extending pins 22. In order to provide horizontal reinforcing for the top portion of plate I an angle member 23 extends across the plate and is secured thereto by means of bolts 24 welded to plate I and ex Fig. l is a front view partly in section and tending through slots 25 in angle 23 and nuts partly in elevation of an enclosure constructed 26. The slots provide for vertical adjustment of 55 angle member 23 which is clamped in position in accordance with this invention. 2 aeeasai to form a recess or groove 21 between the lower surface of underlip B and the upper surface of angle member 23. It is clear that the above back construction permits it to be installed as the trim is prepared for plastering, Later the radiating means may be positioned relative thereto and the front of the enclosure assembled on the back as will be hereinafter described. This construction pro vides a plaster stop so the plaster may be easily brought flush against the sides with the excess iiowing around the edges to present a neat ñn ished appearance. lf it is desired to position insulation between the back plate and the wall this may be readily ber is provided with openings 53 adapted to re reive the rounded end portion of finger 54 for holding the valve in various positions. This enclosure is adapted to enclose any type of heat radiating means which, as illustrated. comprises a hot fluid conducting pipe 55 having heat radiating hns 55. The radiating means has inlet and outlet connections 51 and 58 respec tively (the illustration is for use with a down feed steam line) which extend into the enclo sure through arch shaped openings 3B without in any way being secured to or resting upon any part of the enclosure assembly. The above described form of radiator enclo sure is assembled as is now described. As soon as the steel window sash is installed in the building this can be done. The appropri ate holes 1 must be drilled in the underlip 8 and then the back plate I may be hung thereon with 20 pins 6 positioned in holes 1. The back sheet provide a certain insulating eiîectf' support plate I3 is then adjusted on bolts I5 and Furthermore a back plate so constructed may secured at proper position to bring lip I1 flush be installed as the building is being constructed with upper surface of wood screed I9 to which it and will in no way interfere with the subsequent is then secured by means of screws I8.

The main difference in the construction shown in Figs. 5 and 6 are necessitated by the different form of window sash 9 in which the underlip 8l terminates in a lip 62 uptumed at about 45°. In , such a case the back plate 63 must be formed with an upper edge bent downwardly at sub stantially the same angle as the upturned lip B2, to form a downturned lip 84.
